Figure 6.36. The stretch function
The distortion in figure 6.36 becomes apparent as the
image is pulled l arger . This is because each dot in the original is
expanded to spread the image. There are no smoothing mark s
inserted
to make the image appear more continuou s. This
distortion becomes worse when stretching occurs in only one
direction. It may become unacceptably great when expanding
intricate patterns.
Alternately, shrinking
may cause an image's fine details to
disappear.
The artist may, in some cases, be able to draw
compensatory markings to reduce this distortion , or he or she
may decide simply to redraw the original on a larger or smaller
scale.
